Greater Sandwurm

The fat finisher that fights its own dead-card problem. A seven-mana 7/7 is the kind of top-end threat you never want to see in an opening hand and dread drawing when you're being pressured, so the design bolts an escape valve onto the body: for two generic mana the wurm becomes a fresh card the moment it's stranded. That's the whole bargain, and it's a clean one. It's a closer when you've hit your land drops and a cantrip when you're short on lands or fighting for survival, which means the slot it occupies never costs you a real card. The evasion clause is calibrated rather than absolute: power 2 or less covers the small bodies and tokens that gum up a board stall, while leaving the wurm answerable by anything that trades up, so it taxes attrition without becoming unkillable. Cycling for two rather than one is the tension that keeps the flexibility from being free; a one-mana cycle on a body this large would carry no cost at all, so the extra generic is the price of insurance on a seven-drop. The result asks almost nothing of the deck that runs it: the floor is a replacement-level draw and the ceiling ends games, with no awkward middle where the card is simply stuck in hand.
